Aesthetics and Healing
Back in 1982, I had an aesthetic epiphany when I visited the Alhambra in Grenada, Spain:
Moorish architecture is perfection!
And two of their many guidelines are always offer the sound of running water, and always offer a sense of privacy, especially when there is none.
Their use of fountains, screens, lanterns, mosaics and symmetry are unparalleled. When I try to create healing physical spaces, I always keep the Moors in mind.
